GAS-BURNER FOR HEATING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 260,888, dated July 11, 1882.

Application filed December 9, 1881.

To all whom it may concern:

Be it known that I, JAMES MUSGRAVE, a resident of the city of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Gas- Burners for Heating Purposes, of which the following is a specification.

My invention consists, first, of a burner so constructed as to secure complete combustion of the gas used; and, secondly, of a device for modifying the shape of the flame. The amount of heat developed from a given quantity of gas is proportional to the oxidation of the hydrocarbons of which the gas is composed. The more complete the oxidation the greater the heat developed. To secure this complete combustion the oxygen must be thoroughly mixed with the coal-gas before it reaches the burning-point-that is, the point where combustion is going on. By my device this intimate intermingling of the two gases is accomplished, and aflame of great heat is thereby secured. Furthermore, the complete oxidation of the gases, after being mixed, and while burning, is assisted and the heat increased by an additional supply of air fed to the llame in the manner hereinafter described, and the intensity of the flame is thereby augmented.

In vthe accompanying drawings, Figure 1 represents a side view of my device, the liameregulator being partially broken away to show parts beneath. Fig. 2 is a central section of the same. Fig. 3 shows the ame-regulator in modified form, reversed. Fig. 4 shows the flame-regulator as represented in Figs. 1 and 2, reversed. Fig. 5 is a top'view of the burner, the flame-regulator and burner-cap being removed. Fig. 6 shows a modification of the burner.

The cone A consists of a cylinder, A', across the top of which a. diaphragm, a, extends. Through the center of this diaphragm a vertical cone, af, passes, extending slightly above the diaphragm a and reaching nearly to the bottom of the cylinder A. While this relation ofthe ends of cone a' to the diaphragm a and lower edge of cylinder A is the preferable one, it is not essential, as the cone a may be made flush with the diaphragm a, and extends below the edge of cylinder A.

(No model.)

To the top of the cylinder Al is connected in any suitable manner a cap, preferably hemispherical in form. In the present instance the top of cylinder A is rabbeted, as shown in Fig. 2, for the purpose of securely holding in place the similarly-rabbeted'hemispherical cap B. Cap B is provided with openings b, preferably arranged in a zone about it, through which the mingledair and gas escape.

Extending outwardly from the bottom of cylinder A is a flange, a2, provided on its outer edge with an upwardly-extendin g secondary liange, a3. The flange a2 is perforated With openings (t4, as shown in Fig. 5. The dame regulator or cup O rests on the ange a2, and when in the position shown in Figs. 1 and 2. incloses the openings a4. Itis held in position by the flange a3. As-the cup C extends upwardly it tapers slightly toward its center, being somewhat more constricted near the top. The top of the cup C usually (as in the present instance) reaches somewhat higher than the zone of the dame-openings b. The cone A is preferably supported, as shown in Figs. l and 2, by a yoke, D, from the under side of which (or of a suitable support) a hollow stem, d, extends. Across the top of this stem is a diaphra gm, d', perforated in the center by a small opening, (l2. Into the stem D is screwed a hose-connection, E, to which 'is attached a hose, F. The whole is preferably supported by an arch, G, provided with feet g. rIhis latter arrangement makes the burner portablein fact, makes it a hand gas heater or stove.

The operation of the burner is substantially as follows: The gas, entering through the hose F, passes up through the attachment E and stem d, escaping with considerable 4force through the narrow opening d2 and rushing up through the cone a into thecavity ot' the cap B, from which it escapes through the openings I), where it is ignited. The gas, rapidly escaping through the narrow opening d2, produces a current of air, by which it is accompanied through the cone a'. a and the cavity or chamber above the air and gas are thoroughly mixed, forming a gas in whose combustion the original coal-gas is completely oxidized with the advantages previously set forth. To still further insure an In the cone IOO efticient supply oi' oxygen, the cup (l and openings a4 are provided. Any additional air which may be needed or can be used in burning the gas will rise through the openings co4 and be directed by the cup C into the flame. The cup U has, moreover, another function. In the position of the cup C shown in Fig. 2 it is evident that the flame formed at the openings b would be deflected by it upwardly into a conical or cylindrical flame-such as is seen in an ordinary Argand burner-thus condensing and limiting the heat to a comparatively small area. This limitation ot the iame-area is not always desired,and when a more diffuse iiame isrequired the cup C is to be reversed, as in Fig. 4. In this position it is evident that the iiame does not strike the cup C so soon, and will -consequently be more diffused. Then the cup O is reversed I have several means by which air is admitted between the cup C and cylinder A'. v In Fig. 4 are shown lugs L, each provide with a shoulder, L. These lugs are preferably three in number, and project from the cylinder A at points on its circumference equidistant from each other. In this arrangement the cup C is elevated on the lugs L, allowing air to enter beneath it, and is at the same time held firmly in position by shoulders l, its inner edge being in such relation with them as is shown on the right-hand side of Fig. 4. The cup O is held in this one position for the purpose of keeping its upper (now the lower) edge everywhere equally distant from cap B to thus secure a uniform draft everywhere around the cylinder and a regular symmetrical flame. If the cup were allowed to rest loosely on the flange a2, one part of it would sometimes be nearer to cap B than another, and thus produce an irregular flame. In Fig. 6 the cup C is seen held in position by the shoulders N, and the air is admitted between the cup and cylinder through the openings H. In Fig. 3 the edge of the cup C is shown provided with openings, usually notches c, as shown, for the purpose of admitting air. In this form it is retained in position by shoulders, such as N. (Shown in Fig. 6.)

The advantages of my invention arise from the complete combustion of gas which it effects, thereby enabling one to obtain a greater amount ot heat from a given quantity of gas than can be obtained in any other way, and at the same time economizing by requiring less gas to produce the same quantity of heat which other burners will produce.

What I claim as new and of my invention, and desire to secure by Letters Patent, is-

l. A gas-burner provided with ange a2 and cap B, having perforations I), in combination with the reversible dame-regulator C, one end of which rests on the flange a2, the other end extending above the openings b and so formed that the flame from the openings b will strike against said flame-regulator, substantially as and for the purposes specified.

2. The combination ot' cap B, provided with openings b, cylinder A', cone a', diaphragm c, yoke I), and stem d, provided with contracted orifice d?, substantially as and for the purposes specied.

3. The combination of cap B, provided with openings b, cylinder A', diaphragm a, cone a',

'flange a?, provided with openings a4, cup C,

yoke D, stem d, and oritice d2, substantially as and for the purposes specied.

et. The combination ot' cap B, provided with openings I1, cylinder A', diaphragm c, cone a', iiange a2, provided with orices at, cup C, yoke D, stem d, provided with contracted orilice d?, lugs L, and shoulders l, substantially as and for the purposes specified.

5. 'I he combination of the cylinder A', cap B, provided with opening b, diaphragm a, cone a', flange a2, and cup U, and provisions for introducing the external air into the space be` tween the cylinder A and the cup, substantially as and for the purposes specied.
